Diseño de una planta procesadora para la obtención de pulpa de frutilla en la parroquia San Gerardo del cantón Guano.

Abstract

The present research was carried out for designing a processor plant and to obtain strawberry pulp, in San Gerardo parish, in Guano canton. For the developing was made of recognition and quantification of total production based on the production last years was projected to 5 years, the value obtained load was 125 kg/h. The sampling method was according to the standard respective, experimental part of project that began with the characterization of raw material through sensory analysis as: odor, color, chemical physical appearance pH, soluble solids, density, viscosity, acidity, refractive index, and microbiological analysis, molds and yeasts, total coliforms, fecal coliforms, mesophilic aerobes. The simulation process was carried out at Laboratory of Processes from Faculty of Sciences at Escuela Superior Politécnica de Chimborazo; the design of necessary equipment was approved out for proposed process such as: washing tank, scalding pot, horizontal pulpier, pasteurizer, packer and sealer, cold room for freezing, and secondary equipment: selection tables, conveyor belts and boiler. The validation of product and process was passed out with the NTE (Ecuadorian technical standard) 2337 standard, which establishes physical chemical parameters: minimum soluble solids for strawberries is 6 degrees brix, pH: 3,5, microbiological parameters: molds and yeasts, total coliforms, fecal coliforms, mesophilic aerobes with a value lower than 10 CFU. The equipment is distributed into a plant in a way that guarantees its correct functioning. The proposed process is suitable for strawberry processing, since it assures the innocuousness and quality of the pulp obtained, it is recommended to have a strawberry register as it enters the plant and perform a quality control at the end of each batch produced.
